Anguish good for bishop, in short (5)
I believe the answer is:
brief
'in short' is the definition.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for brief that I've seen before include "Short - work for a barrister" , "Barrister (sl.)" , "Document stating the facts of a legal case" , "Summary of facts for barrister to consider" , "Instructions for barrister" .)
